Thomas is going on a long trip and wants to document it. Should he get a GoPro? Leo says that he can, but the iPhone is really fantastic for shooting now. How does he backup all that video data? Leo says the best option is iCloud, when he's on the road. 200GB only costs about a buck a month. The advantage is that he doesn't have to think about it, it's automatic. And he can set it to backup only when he has Wi-Fi. Leo took the best pictures on his last trip with his smartphone.

Carol-Sue's daughter is going to Zambia with the Peace Corps. She'll have intermittent Wi-Fi connectivity, and no electricity. She wants a solar powered solution to charge her tablet. Leo says that without access to power, it will be a challenge to charge her device. Solar devices will work, but they take a very long time -- several days. Goal Zero makes one, however.

Wayne is going to hike the Pacific Trail, which is about 2,700 miles. He has an iPhone 4 but he needs a charger for it that is both lightweight, portable, and self sustaining. Leo says that he got his son a solar charger, but Wayne needs to understand that they're not terribly efficient and an all day charge may get only get him few hours of phone time.
